2014-02-02rainbows 4.6.1 - EventMachine fixes v4.6.1
* event_machine: update for unicorn 4.8.x * disable cramp tests for now * update EventMachine tests * set executable bit rainbows executable Nothing relevant for non-EM users.
2014-01-29set executable bit rainbows executable
Folks don't usually run from the source directory, but RubyGems complains otherwise.
2014-01-29update EventMachine tests
EM 1.0.3 got released and seems to work under Ruby 2.1, so re-enable EM and NeverBlock tests again.
2014-01-29disable cramp tests for now
Cramp seems broken for now, we'll deal with it at another time and I'm not sure if it ever took off...
2014-01-29event_machine: update for unicorn 4.8.x
unicorn 4.8.x shutdown handling is different and no longer removes items from the event loop. So we must do that ourselves to enable graceful shutdown. Otherwise, we'll time out on shutdowns and the master will forcibly kill us.
2014-01-17Rainbows! 4.6.0 - fix unicorn 4.8.0 compatibility v4.6.0
The unicorn 4.8.0 internal changes unfortunately broke some unoffically supported behavior we depended on. This release fixes that, but as a result, we lose compatibility of older unicorn versions. (Oops!, oh well... :x) There's also minor bugfixes and documentation updates. In order to ease transitions to future versions of the GPL, we are now "GPLv2 or later" instead of explicitly GPLv2 + GPLv3(-only). The old Ruby 1.8 license remains an option. If the FSF turns out a horrible GPLv4, users are free to continue using GPLv2 or GPLv3.
2014-01-17switch homepage to http://rainbows.bogomips.org/
RubyForge is going away, so we must migrate the homepage. The mailing list will be migrated, soon.
2014-01-17unicorn 4.8 compatibility + test version bumps
Internal reworking of unicorn 4.8.0 completely broke us(!). This commit fixes things, but it means we no longer support unicorn <= 4.7. Sorry about that.
2014-01-17error: silence ETIMEDOUT and EHOSTUNREACH errors
There's nothing we can do about these errors due to network failures and bad clients, either, so do not spew a backtrace for them.
2013-10-26license: allow all future versions of the GNU GPL
There is currently no GPLv4, so this change has no effect at the moment. In case the GPLv4 arrives and I am not alive to approve/review it, the lesser of evils is have give blanket approval of all future GPL versions (as published by the FSF). The worse evil is to be stuck with a license which cannot guarantee the Free-ness of this project in the future. This unfortunately means the FSF can theoretically come out with license terms I do not agree with, but the GPLv2 and GPLv3 will always be an option to all users.
2013-09-30Rakefile: kill raa_update task
RAA is dead.
2013-09-13Match against newer curl.
My curl 7.32.0 would actually print 400 Bad Request Hope this would make it match against newer or older curl. Signed-off-by: Eric Wong <normalperson@yhbt.net>
2013-09-04SIGNALS: document SIGHUP/preload_app incompatibility
This was documented in the unicorn docs, but not Rainbows! (The major difference between unicorn and Rainbows! signal handling is the deferred handling of SIGUSR1 in unicorn vs the immediate handling in Rainbows!)
2013-04-24test_isolate: update raindrops to 0.11.0
raindrops 0.11.0 was released several days ago and contains minor improvements + fixes.
2013-03-01epoll+xepoll: clarify intent of these concurrency options
Via private communication, I learned of a user using XEpoll when he should not have been.
2013-02-27Rainbows! 4.5.0 - hijacking support v4.5.0
This release adds hijacking support for Rack 1.5.x users. See Rack documentation for more information about hijacking. Lin Jen-Shin also provided the -N/--no-default-middleware option. Minor packaging cleanups and new HACKING document. There are also some corner-case bugfixes for *Epoll* users (sleepy_penguin, these bugs do not affect EM or Cool.io users) and test suite portability improvements.
2013-02-26manpage: update middleware-related documentation
-N/--no-default-middleware needs a corresponding manpage entry. Additionally, the Rack::Chunked/ContentLength middleware comment is out-of-date as of unicorn v4.1.0
2013-02-26epoll/*: remove user-space array as active queue
This prevents pathological starvation cases where the user-space ready-list can be repopulated infinitely. With EPOLLONESHOT, epoll itself may be used for this task (at a slightly higher cost) by enabling read/write checks, as the epoll ready-list preserves event ordering when used with EPOLLONESHOT.
2013-02-26xepoll_thread_*/client: EPOLLONESHOT implies EPOLLET
No need to specify both flags for epoll (confirmed by reading fs/eventpoll.c in the Linux kernel).
2013-02-26doc: add HACKING document
Thanks to Alex Wolfe for noticing.
2013-02-26tests: update checks for Ruby 2.0.0
EventMachine/NeverBlock currently do not build on Ruby 2.0.0
2013-02-26bump unicorn dependency to 4.6.2+ for Ruby 2.0.0
This ensures we're compatible with the latest stable Ruby version.
2013-02-26gemspec: set licenses= attribute
Old versions of RubyGems which could not handle this attribute are likely no longer in use.
2013-02-16GIT-VERSION-GEN: rewrite to manage RAINBOWS_VERSION const
This DRYs up versioning and makes packages easier to distribute.
2013-02-11hijacking support for Rack 1.5.x users
This requires Rack 1.5.x and unicorn 4.6.0 for hijacking support. Older versions of Rack continue to work fine, but we must use unicorn 4.6.0 features to support this.
2013-02-04tests: "wc -l" portability for *BSDs
On FreeBSD 9.0, "wc -l" emits leading whitespace, so filter it through tr -d '[:space:]' to eliminate it.
2013-02-01tests: bump version dependencies for Isolate
Most of these test dependencies may be safely bumped.
2013-02-01tests: "wc -c" portability for *BSDs
On FreeBSD 9.0, "wc -c" emits leading whitespace, so filter it through tr -d '[:space:]' to eliminate it.
2013-02-01tests: replace non-portable "date +%s" with ruby equivalent
"date +%s" is not in POSIX (it is in GNU, and at least FreeBSD 9.0, possibly earlier). The Ruby equivalent should be sufficiently portable between different Ruby versions. This change was automated via: perl -i -p -e 's/date \+%s/unix_time/' t/*.sh
2013-02-01tests: remove utee and use tee(1) instead
POSIX already stipulates tee(1) must be unbuffered. I think my decision to use utee was due to my being misled by a bug in older curl where -N did not work as advertised (but --no-buffer did).
2013-01-29Add -N or --no-default-middleware option.
This would prevent Unicorn (Rainbows) from adding default middleware, as if RACK_ENV were always none. (not development nor deployment) This is implemented in Unicorn, so we only need to update the option parser here.

2013-01-24epoll: ensure closing of pipelined clients if required
on_read normally relies on the close checking in on_readable, but on_deferred_write_complete may be called from on_writable instead (bypassing the close check of on_readable). This affects both Epoll and XEpoll users, but only if they were sending responses via body#to_path and triggering on_deferred_write_complete. While we're at it, favor non-recursive want_more instead of calling on_readable recursively in ev_write_responses to prevent stack growth.
2013-01-18Rainbows! 4.4.3 - bugfixes for EventMachine users v4.4.3
This release fixes two EventMachine bugfixes from Lin Jen-Shin and Mark J. Titorenko. There are also some minor cleanups. Lin Jen-Shin (1): event_machine: avoid close on deferred response Mark J. Titorenko (1): event_machine: join reactor_thread if it is already running Eric Wong (2): event_machine: cleanup confusing assignment t/GNUmakefile: cleanup test dependencies
2013-01-17t/GNUmakefile: cleanup test dependencies
The missing random_blob dependency was causing the following to fail on a fresh clone: make -C t ThreadPool.t0005-large-file-response.sh
2013-01-11event_machine: join reactor_thread if it is already running
...rather than falling through worker_loop Prior to the application of this patch, if an EventMachine reactor_thread has already been started elsewhere before the worker_loop is entered, the worker_loop exits as a second call to EM.run does not block the current thread. This patch causes the worker_loop thread to join the reactor_thread if it is running. [ew: commit message formatting] Signed-off-by: Eric Wong <normalperson@yhbt.net>
2012-12-19event_machine: cleanup confusing assignment
2012-12-18event_machine: avoid close on deferred response
close_connection_after_writing only if not deferred, as in cool.io Deferred responses may buffer more data down the line, so keep the connection alive if we have a deferred response body. [ew: clear @deferred when we really want to quit, updated commit message] Acked-by: Eric Wong <normalperson@yhbt.net>
2012-12-06Rainbows! 4.4.2 - EventMachine async.callback fix v4.4.2
One bugfix allows stream(:keep_open) in Sinatra to work properly. Thanks to W. Andrew Loe III for the informative bug report and reproducible test case. ref: http://mid.gmane.org/CA+-9oNd1EFqsniPkkPTwu5opTCinbM7-2KHoXov7+y3LE4s4Tg@mail.gmail.com
2012-12-05test_isolate: bump eventmachine and sinatra deps
Always ensuring we work with the latest versions.
2012-12-05event_machine: properly defer body.close for async
Calling body.close in the normal write_response() code path is incorrect, and only worked out of sheer luck with Cramp and async_sinata. This change allows stream(:keep_open) in Sinatra to work properly. Thanks to W. Andrew Loe III for the informative bug report and reproducible test case. ref: http://mid.gmane.org/CA+-9oNd1EFqsniPkkPTwu5opTCinbM7-2KHoXov7+y3LE4s4Tg@mail.gmail.com
2012-08-31Rainbows! 4.4.1 - a minor bugfix for Fiber users v4.4.1
Fiber-based concurrency options avoids negative sleep intervals. Thanks to Lin Jen-Shin for pointing this out.
2012-08-27fiber/base: avoid negative sleep interval
Also clarify the code while we're at it. Thanks to Lin Jen-Shin for pointing this out. ref: http://mid.gmane.org/CAA2_N1unOXb7Z4Jr8oKoSLu266O9Ko4o=oWzAcMA1w3=9X74KA@mail.gmail.com
2012-08-18Rakefile: freshmeat.net -> freecode.com
freecode.com now requires HTTPS, too.
2012-08-18Rainbows! 4.4.0 - minor improvements v4.4.0
For epoll/Cool.io-based concurrency models, shutdown() is now used to timeout keepalive clients to avoid race conditions. Minor documentation improvements.
2012-07-19thread_timeout: document additional caveats
Again, for the one thousandth time, timing out threads is very tricky business :<
2012-07-01test_isolate: bump raindrops dependency
As usual, test with the latest released version to avoid surprises.
2012-07-01coolio+xepoll_thread*: use shutdown() for keepalive timeout
Triggering Errno::EBADF is tricky in multithreaded situations due to possible race conditions and yet-to-be discovered bugs. shutdown(2) is also safe against apps the fork() internally but do not execve(2) nor set FD_CLOEXEC. n.b. calling fork() after pthreads are spawned may not be safe on all platforms w.r.t. malloc, but /is/ the case for glibc on GNU/Linux. Follow-up-to: commit a5b987619f4b793203f6a50e424fe98c5b0794ba
2012-06-18epoll*: favor shutdown(2) for keepalive timeout

2012-05-09fiber_pool: take Fibers from larger pools faster
Array#pop can be significantly faster than Array#shift on large arrays (especially since we push into the Array). This is because Array#shift needs to shift all elements in the array, and Array#pop only needs to shorten the array by one element. The Fiber stack may also be hotter in CPU caches when we choose the most-frequently used stack.
2012-05-09test_isolate: update deps for EM tests
async_sinatra and rack-fiber_pool had new versions since we last updated.
